Here's a little fun reading for you. It's a link to a thoughtful blog called The Sci-Fi Catholic. D.G.D. Davidson is writing a three part essay called The Vivsection of Bone, Part One: Romancing the Bone, about the romantic relationship between Fone Bone and Thorn. It's filled with references to literature, mythology and Arthurian legends. The analogy to Tristan and Isolde is especially interesting.
Another sharp site that discusses comics, sci fi and fantasy from a particular perpsective is FemiNerds. Their mission statement reads: "Two women who feel the need to share their views on feminism and science fiction, fantasy and horror with the world. Because we can."
The FemiNerds have posted their list of the Top 12 Graphic Novels they recommend to their readers. You can also download their very first podcast. It's a point of view we don't have enough of in comics.
